What Geiger Brothers does

Geiger Brothers, Inc. is a 116-year-old, employee-owned multidisciplinary construction and engineering firm headquartered in Jackson, Ohio. The company self-performs Mechanical, Electrical, and Plumbing (MEP) construction work through a team of 400+ craftspeople, operating across Ohio, Kentucky, West Virginia, and Tennessee with additional offices in Hilliard, Ohio and Oak Ridge, Tennessee. Geiger serves highly regulated end markets including nuclear, institutional/education, healthcare, infrastructure, power, commercial, and industrial customers.

The company's offerings are organized into five integrated service lines: Construction (self-performing MEP plus specialized QL-1 nuclear services), Fabrication (piping, sheet metal, and ASME/NRC-compliant off-site manufacturing from an 18,000 SF Jackson facility that is currently being expanded), Engineered Solutions (pre-construction, program management, design-assist, design-build, Virtual Design Construction, and shared BIM collaboration), Service & Maintenance (preventive maintenance and 24/7 emergency MEP service supported by a fleet of 150 vehicles), and UL 508A Industrial Control Panels (HVAC control, industrial control, and power distribution panels produced by 8 UL-certified technicians in-house). The firm maintains QL-1 nuclear supplier status with compliance to ISMS, 10 CFR 851, NQA-1, and 10 CFR 50, alongside UL 508A panel certification — a regulatory stack that materially constrains competitor entry.

Geiger generates revenue through project-based construction contracts (one-time), professional engineering and design services, recurring service and maintenance agreements, one-time fabrication work, and hardware sales of UL-certified industrial control panels. Pricing is quote-dependent rather than published. Go-to-market is enterprise field sales via direct owner relationships and subcontractor positions, supported by design-assist and design-build delivery models. The company is led by CEO Scott Massie (in role since 2013, owner since 1991), President & CFO Erik Massie, P.E., and COO Kyle Hickey, P.E. It became 100% employee-owned through an ESOP in 2023 and is currently executing a multi-billion-dollar construction role for Centrus Energy at the American Centrifuge Plant in Piketon, Ohio, under Fluor Corporation as EPC contractor.

Direct peers

• Limbach Holdings: Public specialty MEP contractor focused on building systems for institutional, healthcare, and commercial customers. Directly comparable in core MEP self-perform model, customer mix, and project-based services revenue.
• IES Holdings: Electrical and mechanical contractor serving industrial, commercial, and institutional markets. Closely comparable business mix (MEP self-perform, industrial focus, recurring service revenue) and similar customer profile.
• MYR Group: Specialty electrical construction services provider with strong transmission/distribution and commercial & industrial presence. Comparable in craft-driven specialty construction, self-perform model, and project-based revenue.

Broad incumbents

• EMCOR Group: Largest publicly traded U.S. mechanical & electrical construction and facility services firm. Overlaps heavily with Geiger's MEP, service & maintenance, and industrial/nuclear work but at national scale and broader portfolio.
• Comfort Systems USA: National mechanical contractor providing HVAC, plumbing, and related services. Competes with Geiger in commercial, institutional, and industrial segments, with much larger regional reach and balance sheet.
• API Group: Safety, specialty, and industrial services holding company with significant MEP, HVAC, and life-safety services exposure. Overlaps with Geiger's industrial and nuclear facility-services capabilities.
• Quanta Services: Largest infrastructure construction firm focused on electric, oil & gas, and telecom. Adjacent peer via energy/power construction and skilled-craft workforce parallels.

Others

• Fluor Corporation: Global EPC contractor and Geiger's prime on the Centrus Energy Piketon project. Not a direct competitor on craft MEP work but a critical counterparty and channel to federal/nuclear customers.

Regional players

• Baker Construction: Large privately held concrete and general contractor operating across the Midwest and Southeast. Comparable as a regional multi-discipline self-perform construction firm with similar geographic concentration.
• Lithko Contracting: Privately held specialty concrete and foundation contractor operating across the Midwest and Mid-South. Comparable as a craft-intensive regional self-perform firm serving similar institutional and industrial customers.
